SUSE - What's New
Suse Rancher, Harvester, Liberty, and more!
==================================================

SuSE Liberty is a replacement for CentOS.
From https://www.linuxadictos.com/en/suse-alternative-centos-liberty-linux.html
from 21 Jan 2022

CentOS was one of the most acclaimed distros for servers, and one that many companies adopted, a binary fork of RHEL (Red Hat Enterprise Linux), from Red Hat (now owned by IBM), maintained by the community and free.    But nevertheless, in an unexpected turn (by RedHat), everything was turned upside down, leaving a large gap that is now to be filled.   (The CentOS that we knew is no more.)    Liberty Linux from SUSE, is another of the alternatives that join projects like AlmaLinux, Rocky Linux, etc.    ...   ...   ...

Liberty Linux is a distro that is being developed by SUSE with its own Open Build Service tool, from the binary packages Official Red Hat RPMs (SRPMs).    In the case of the kernel, the RHEL kernel will not be used, rather it is based on the SUSE Linux Enterprise Server (SLES) kernel, but compiled using a configuration to maintain compatibility for RHEL/CentOS.

==================================================
What is SuSE Harvester?
What is rancher vs Kubernetes?

SUSE Rancher is a container management platform that provides full management of all your Kubernetes distributions, whether you're managing one or one ... SUSE Rancher addresses the needs of DevOps teams deploying apps.

The difference between Kubernetes and Rancher is:
	* Kubernetes is a technology for managing containers
	  organized under a cluster of virtual or physical
	  machines.
	* Rancher is a technology for managing Kubernetes clusters
	  en masse.

Harvester= Open, interoperable hyperconverged infrastructure HCI

Hyperconverged infrastructure (HCI) doesn’t need to be expensive or complex and with Harvester it’s not.   Harvester presents organizations with a modern HCI solution that is feature-full and purpose built for cloud-native environments.   Consolidate your virtual machine workloads and Kubernetes clusters with Harvester.

Designed by the SUSE Rancher engineering team, Harvester is built on Kubernetes and utilizes the latest cloud-native solutions

Harvester has two modes of operation:

	* HCI, where it can attach to another cluster as a VM hosting node
	or
	* a Helm application deployed into an existing Kubernetes cluster.
